It is one thing to reprimand people in public and another thing to be emotionally abusive about it. Steve Jobs is famous for being absolutely confident of himself (even for things that he didn't really know about) and for expecting the impossible from his employees (and being verbally abusive about it). This is a recipe for surrounding yourself with yes-men and for making your employees behave defensively when they are around you. Another thing is that people, like most animals, are better encouraged by positive reinforcement than by punishment.
